` Application lcd August 13, 1909. Serial No. 512,114.

To all whom it may concern:

Be it known that I, Ennemi BENDER, a subiiect of the Kingof'Prussa,residing at Mo tkestrasse 2, Hagen, Germany, have 1n- 5 ventedcertain new and useful Img'ovements in Re enerators; and I do here ydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it ap-1oV pertains to make and use the same, reference eiug had to the'accompanyin drawings, andto letters of reference mar ed thereon, whichform a part of this specification.

`My invention relates to air heaters or reases are caused to becontinuously led t rough a series of passages formedv of tile or brick,said tile or brick4 assages bein simultane- 'ously surrounded y air tobe eated passin continuously through the regenerator sit er parallelwith or in counter-current to the furnace heating ases, the specificconstruction of which w1 l hereinafter 'be more fully explained withreference to the accompanying drawings in whichlike parts are similardesignated, and in which- Figure 1 is a vertical longitudinal section onthe line G-H of Fi 3. Fi 9. is a horizontal section on the ine A ofFi 1. Fig. 3 is a section taken on the line C of Fi 2 and Fig. 4 is 'asection taken on the line L-F of Fig. 2, while Fig.'5 4is a sectionsimilar to Fig. 4 showing a modification.

Thecasin for the regenerator comprises suitable bric work or walling a,on the bot-A tom of which are placed rows of tile or briclf spaced a arttransverselyxso as toV form longitudina passages lo' between them. 0nthese ro'w's of tiles f are supported tile 40 having lateral rabbets, orin other words are T-shaped, the larger ones h of whichV cover thespaces between the tile f and the smaller ones or spacing tile g ofwhich` rest on the tile f, the tiles g and h alternating across theregenerator, thereby forming grooves between the abutti g rabbeted sidesof Ithe tiles h, and g. In hese grooves are set other tile 'isubstantially perpendicular to those g and h, which tile in turn arecovered with inverted tile g and h thereby forming longitudinal passagesd and smaller longitu ina'l parallel passagps k, one on each side of thepassages d. T e structure thus described forms a unit, any 4number of 65which may be assembled with respect to one another ,to increase thenumber of passages d and c and as shown in Fig. 3 three such units'havebeen assembled to orlu a rcctan ular regeuerator.

T e larger longitudinal passa es d terminate at one end in an inlet chamer b and at the other end in an outlet chamber c, the gases from ansuitable source being led to the chamber through the passage d outthrough the chamber c to the stack or like. i

The smallerassages la are somewhat shorter than tose d and terminate ata chamberm. at one end and a chamber Z at Vthe other end, there beingsuitable openings left in one side of the rectangular regenerator casinto communicate wlth said chambers m an l. By omitting the tiles f and gat the chambers m and l, fonexam le, as shown in Fig. 4, just above thechamber m, the air can pass around on all sides of the longitudinalflues d and enter the longitudinal air passages k. These longitudinalair passages k terminate at l in the same manner as shown with respectto the entrance chamber m. The air-enters the chamber m and has its exitat Z, e., is a counter-current to the furnace ases. The oppositedirection of the dow otg the air maybe attained by reversin the intakefrom m to Z.

In ig. 5, I have shown amodification in which t e tile or brick h and 'ihave rounded corners thereby oiering less resistance to the air in-itspassage through the assages k of the regenerator that surround hepassages 90 he tile or brick may be arched when constructing thepassages d of large cross sectional area without departing from thenature of my invention.

The regenerator shown is of the horizontal t'ype, where the ases and airare passed horizontal] 4throu the regenerator, it is of course o vious tat the same construction may be made vertical.

claim 1. A regenerator com rising one or more units, each composed overtical tile spaced apart and -horizontal tile forming longltudinalchannels, s acing tile se arating the horizontal tile rom one anot erwhereby said channels are surrounded by channels, an entrance chamberand an exit chamber for the longitudinal channels and an entrancechamber and an exit chamber for the spaces -between said channels,communieating with the s aces between the channels, saidcommunicatlonbeing formed by omitlois ting the spacing tile between them at. theirentrance and exit ends.

2. A re enerator comprising one or more units, anni composed'of rows offlat tile spaced from one another, tile spanning the spaces between theaforementioned tile, having lateral rabbets and spacing tile alterhatingwith said rabbeted tile also having lateral I'abbets, Hat tile mountedin the grooves formed by the adjacent rabbets end inverted rabbetd tileand spacing tile, an inlet and un exit chamber communicating with thechannels formed by the larger tile and an inlet nd an exit chambercommunicating with the `spaces formed on each side of the channelsformed by the larger tile.

3. In a re enerator, a unit comprising flat .tile spacedA rom oneanother, tile spanning the spaces between Vthe -aforementioned tilehaving'lateral rabbets on one face, flat tile perpendicular to therbbeted tile mounted 1n the rabbets thereof to form rectan ular passaes, the corners of said` tile ing roun ed to forni rounded outer cornerson the passages so formed.

In testimony that I claim the foregoing as my invention, I have signedmy name 'in presence of two subscribin Witnesses.
